## Abstract Two‐to five‐bond ^15^Nο£Ώ^19^F coupling constants have been determined for fluoropyridines, 8‐fluoroquinoline, fluoroanilines and fluoroaniline derivatives. Only in 2‐fluoropyridine is __J__(NF) large, and this is associated with a lone pair mediated enhancement of the coupling. Values in
